[PATCH 0/3] net-next: stmmac: support future possible different internal phy mode

It is too late when we know the PHY ID.
We need to set a syscon for choosing external/internal PHY.
So we can rely only on DT.

The point is, its not a property of the PHY. It is a syscon or a MAC
property. Having it as a MAC property would be more generic.
